What do you want to do?
If you go before memorial dat you run uno low season where some places could be closed if ski stops in mid April then summer starts in early June.
i woukd suggest 2 other pkaces
1 aspen. Take bus in a morning to maroon bells. Aspen is very walkabke with an airport.
2 ouray. Ouray is a town that opens from Memorial Day weekend through end of September many of staff shift from telluride to ouray to work in the summer. It’s walkabke and there are many hiking sites around town as well as off road touring companies and some.
